Building a small transmitter? Something QRP that fits in an old pen?
The 3x8 mm cylindrical crystals make that project easier than ever. These
tiny crystals have been put to use in all kinds of low power, 100 milliwatts
or less, circuits. These are the same crystals we use in our Time Machine
receiver and they work great.

We also carry HC49 crystals. They are our most popular size and are available
in several new frequencies. Our HC49s are now being utilized in most of the
popular small QRP transmitters and transceivers.

Below you will find a list of the frequencies available in each size. When
ordering remember to note HC49 or Cylindrical with the frequency.

All of our quality crystals come directly to us from the manufacturer. We
order in large lots for each frequency and pass the savings on to you. If
you have a need for a large number of crystals on a special frequency please
let us quote your next projects needs. Minimum orders start at 100 per
frequency with added savings the quantity increases. Send us an email with
the crystal frequency and other specifications and let us quote these for
your next project.
